Superconducting fault current limiter development

IEEE Transactions on Magnetics, 1991
The authors have developed and tested a 400-V 100-A-class fault current limiter wound with AC superconducting wire with ultrafine NbTi filaments. The limiter consists of noninductively wound superconducting trigger coils and a superconducting limiting coil which acts as a reactor.

A superconducting fault-current limiter

Journal of Applied Physics, 1978
A conceptual design is presented for a fault-current limiter for the electrical power utilities which utilizes a superconducting element to commutate the fault current into a shunt resistor. The technical feasibility of the concept is supported by a computer simulation of the switching.

Superconducting fault current limiters

IEE Colloquium on High Tc Superconducting Materials as `Magnets', 1995
Fault current limiters (FCLs), superconducting or otherwise, have the potential to reduce fault levels on electricity power networks, and may ultimately lead to lower rated components (i.e. cheaper) being used, or to increased capacity on existing systems.

A practical superconducting fault current limiter

IET Conference Publications, 2009
This paper discusses the increasing requirements for an effective means of controlling fault levels on electrical networks and describes the work by Rolls-Royce and partners to develop a practical superconducting fault current limiter. Practical superconducting fault current limiters require materials with a high tolerance to mechanical process ...

Towards the superconducting fault current limiter

IEEE Transactions on Power Delivery, 1991
The advent of low-loss AC superconductor wires opens the way to a new current limiting technique: that of extremely fast transition from a superconducting state to a resistive state when the fault current exceeds the conductor's critical current. A 25 kV single-phase prototype is described which consists of a Nb Ti superconducting coil without iron ...
